Is it normal to hate people?

Not only do i hate people but i especially hate when they are around me but every so often i'll need to be around someone i enjoy to some extent, but after being around said person for just a little bit i get my normal feeling that covers my entire body and will only go away when i'm finally alone again.

What i'm trying to say is that 98% of the time i want to be left alone, but when i want to be around people there is either no one around (not surprising) or if there is someone around and i end up being around them i can only do so for like 5-8 hours before i want nothing to do with them... How can i maintain friendships with people if i'm like this? Or even worse having a girlfriend? In a few months my girlfriend was going to buy a house and have me move in with her, how TF do i love with someone if i love solitude so much? I feel like it isn't going to work out but then again if you knew her you would see why i love her so much.
